Rings and Domes


Clear and Opaque DomesTypically available in NitroSil or PyroQuartz. Other materials available by special request.  Pyromatics manufactures high purity fused quartz semiconductor processing equipment components including, but not limited to coil covers for GEMINI epitaxial reactors, rings, domes, coil mounting plates, lower coil plates, base plates and coil support plates. 

Our products are made by a patented molding process for greater strength and durability.  Unlike conventional quartz products that are fabricated with hand-welded corners, Pyromatics’ products feature seamless, one-piece construction with rounded corners and uniform wall thickness.  Molding eliminates welded seams that create areas of high stress susceptible to chipping, distortion and breakage.  The uniform wall thickness of Pyromatics’ products contributes to a stronger, more durable part, that has significantly longer life.
